Help identifying 9x19 MFS


#1

I have an older looking box of MFS 9mm Parabellum that I’m trying to get more information on. The thing I’m most interested in is the manufacture year. The headstamp only says MFS 9x19. I’ve seen other boxes with more information printed on them, but mine doesn’t have much. There is an ink stamp on the inside of the opening flap that says “94 31”. There is also a curiously whited-out line in the description on the outside of the box. Any information is appreciated!
